Mesh generation using CENTAUR

Abstract

CFD in realistic geometries requires complex meshes. Among the many commercial knitters on the market, CENTAUR is particularly powerful for unstructured meshes. It is therefore a good candidate for meshing complex geometries.

Objective of the training

The objective of this training is to learn mesh generation techniques, especially for unstructured and hybrid meshes using the CENTAUR software.

Learning outcomes

At the end of the training, participants will be able to:

Use CENTAUR via the graphical interface.

Import a geometry, clean it and put in data the boundary conditions.

Create the sources of refinement, whether they are surfacic or volumic.

Generate a first mesh and have a critical look at the number of cells and smallest cell volume.

Evaluate the quality of the mesh and know how to clean it.

Target participants

This course is intended for anyone in the field of CFD (engineers, doctoral students, postdocs, trainees) wishing to mesh any geometry under Centaur. The target is primarily internal aerodynamics, not external (aircraft wing for example).

Prerequisites

Basic knowledge of what a mesh is and preliminary notions of CFD.

In order to follow this course, you need to:

be familiar with the use of basic Linux commands.

In order to verify that the prerequisites are satisfied, the following questionnaire must be completed. You need to get at least 75% of correct answers in order to be authorized to follow this training session. If you don't succeed it, your subscription will not be validated. You only have two chances to complete it.

OASIS3-MCT is a coupler of codes developed at Cerfacs and used around the world, mainly for climate modelling applications. Our last survey confirms that OASIS3-MCT is used by 67 modelling groups to assemble more than 80 different coupled applications over the 5 continents. These applications include global or regional configurations of ocean and atmosphere models but also sea ice, sea level, wave, ocean biogeochemistry, land, vegetation, river routing, hydrological and atmospheric chemistry models. OASIS3-MCT is used in 5 of the 7 European Earth System Models participating to the 6th Coupled Model Intercomparison Project (CMIP6) that produces the climate simulations forming the basis of the next report of the Intergovernmental Panel on Climate Change (IPCC)”Read more

The annual Sparse Days meeting will be held at CERFACS in Toulouse on 11th and 12th July 2019.
Registration for the Sparse Days is free but we ask people who are coming to register as soon as possible although the deadline is June 14th. Please complete the registration form (deadline : June 14th) indicating whether you want to give a talk and whether you wish to attend the conference dinner.
Although an emphasis will be on parallel aspects, any talk that has an association with sparsity is welcome.Read more
